Use previous time step solution in a function

I want to build an external function solving some stuff by finite differences. I need to give the solution of the previous time step to my function. Do you know how to get these solution in COMSOL ? Is there something like Ut or Ux for the time or space derivative of U ?
I will also need the value of the time step.
I know I can do this using Matlab scripting, but the Matlab API is very very slow, so useless for optimization purpose.
Thanks a lot for your help !
